Selection of Sedimentation Basin Shapes

There are many sedimentation basin shapes. They can be rectangular, circular, and square.

1. Rectangular Basins

Rectangular basins are commonly found in large-scale water treatment plants. Rectangular tanks are popular as they tend to have:

  • High tolerance to shock overload
  • Predictable performance
  • Cost effectiveness due to lower construction cost
  • Lower maintenance
  • Minimal short circuiting.

2. Circular and Square Basins

Circular basins are frequently referred to as clarifiers. These basins share some of the performance advantages of the rectangular basins, but are generally more prone to short circuiting and particle removal problems.

For square tanks the design engineer must be certain that some types of sludge removal equipment for the corners are installed.

NB: Note that whereas most of the above facts concern water treatment, most of them still obtain in waste-water treatment, hence the need to have them discussed under this unit.
